Want to see The Rolling Stones play for free? That may be the stuff of daydreams: unless you happen to be traveling to Cuba this weekend.

Today—Friday, March 25—Mick Jagger, Keith Richards, Charlie Watts, and Ronnie Wood are taking the stage in Havana to perform the country’s first-ever open-air British rock concert.

“We have performed in many special places,” the band said, “but this show is going to be a landmark event for us.”

The Stones have a reputation for playing enormous—and free—concerts. Just 10 years ago, they played for an audience of 1.5 million people on Copacabana Beach in Brazil. According to Mashable, as many as 500,000 fans will fill the Ciudad Deportivo sports centre. After all, there are still travel regulations in place, and airlines haven't resumed regular service there yet. But the show will undoubtedly be one for the history books.

In addition to entertaining Cubans and travelers from around the world, The Rolling Stones are also leading an initiative to to provide instruments and equipment to Cuban musicians, whether they're rock 'n rollers or salsa performers.
